Peugeot 3008 AC issue

Hi, I'm having an A/C issue with my 2015 Peugeot 3008 (gasoline engine, 81749 km). The air conditioning system doesn't switch on, so it's no longer cooling. The error memory stores an error, which I suspect is related to an undervoltage. Does anyone have experience with A/C compressor shut off?

A 2015 Peugeot 3008 is experiencing an air conditioning issue where the system fails to switch on, suspected to be due to an undervoltage error. Possible causes include a refrigerant leak or a faulty AC relay switch. The problem was resolved by re-adjusting the electronics and replacing the relay switch, restoring the A/C functionality.

Did this summary help you solve your problem?

Oh, I feel your pain. I had similar problems with my old Opel Corsa! The AC just decided to quit on a long trip. Did you check the pressure sensor? Maybe there is a refrigerant leak. I would also check the AC relay switch. I was so frustrated back then!

Thanks for the tip, I will check the refrigerant. Which AC relay switch did you mean? There are several relays in the fuse box.

Yeah, sorry, should have been more specific. I meant the main one for the AC compressor. I'm no expert, but after a bunch of trial and error, I eventually had to take it to a workshop. They diagnosed the issue pretty quickly.

Thanks for sharing your experience. It turned out to be an undervoltage and after re-adjusting the electronics and replacing the relay switch, the A/C is now running again. Cost me 240€ at the local shop.
